High Entropy Materials: Fundamentals and Potential Applications

An-Chou Yeh is a Professor of Materials Science and Engineering at National Tsing Hua University and the Director of the High Entropy Materials Center in Taiwan. He specializes in alloy design, high-entropy alloys, superalloys, thermo-mechanical processing, single-crystal growth, and additive manufacturing. He earned his MEng from Imperial College London (First Class Honours in Aerospace Materials Engineering) and his PhD in Materials Science and Metallurgy from the University of Cambridge. He previously worked at Japan’s NIMS on advanced Ni-based superalloys. A pioneer in high-entropy superalloys, he has received several honors, including the Marcus A. Grossman Young Author Award from ASM International, the Excellent Young Engineer Award from CSME Taiwan, the Mercator Fellowship from the German DFG, and the Excellent Young Academic Researcher Award from MRS-T Taiwan.

Tsai-Fu Chung is an Assistant Professor in the Department of Materials Science and Engineering at National Yang Ming Chiao Tung University (NYCU). He specializes in employing advanced electron microscopy―including atomic-level Cs-corrected TEM and 4D-STEM techniques―to unravel the microstructure-property relationships in structural materials. His research has made significant contributions to the field of high-entropy alloys (HEAs), with a particular focus on the strengthening mechanisms and deformation behaviors of FCC-based HEAs under extreme environments, such as cryogenic temperatures and high strain rates. Beyond HEAs, his expertise extends to high-strength aerospace aluminum alloys and super-bainitic steels. Prior to joining NYCU, he held postdoctoral positions at National Taiwan University. He is a recipient of the National Applied Research Laboratories Outstanding Achievement Award and multiple Young Scientist Awards for his work in microscopy and physical metallurgy.

Jien-Wei Yeh is a pioneering materials scientist whose expertise spans aluminum and magnesium alloys, metal matrix composites, metallic glasses, coatings, reciprocating extrusion, and high-entropy materials (HEMs). Since 1995, he has led groundbreaking research that redefined alloy design by proposing material compositions beyond traditional boundaries, unlocking vast compositional possibilities across the Periodic Table. He coined and defined “high-entropy alloys (HEAs),” established their four core effects, and laid the theoretical foundation for this rapidly expanding field. His work further extended high-entropy concepts to ceramics, polymers, and composites, catalyzing global development of high-entropy materials. He has been elected as an academician in Academia Sinica, and has received many prestigious awards, including the Executive Yuan Award for Outstanding Science and Technology Contribution (2021) and the Taiwan Presidential Scientific Award (2025). In Stanford’s global rankings in scientific influence, he ranked second worldwide in Materials.

Devesh Misra is the Dean of College of Engineering, and a Professor from the Department of Biomedical Engineering and Department of Mechanical, Robotics, and Industrial Engineering, Lawrence Technological University. He earned his metallurgical engineering degree from IIT (BHU) and his PhD from the University of Cambridge. He began his career at India’s Defense Metallurgical Research Laboratory, later holding major academic leadership roles including endowed chair, center director, department chair, and graduate program director at multiple R1 universities. His work spans mentoring students and faculty, building interdisciplinary research programs, fostering global exchanges, leading university–industry partnerships, and engaging alumni and community networks. From 2001–2024 he directed numerous federally and industrially funded R&D projects. He also pioneered project-based education and continues to promote innovative, cross-disciplinary learning. He has published over 1000 peer reviewed articles in journals.
